Gay men: is your preference for top, bottom, or versatile deep-seated and natural, or a free choice?

hmm, im a gay guy, i just checked. ... my index and ring fingers are the same lenght. the index finger is about a centimeter longer than the ring finger. and im kind of the same way u are 2. im bottom, and almost all of my freinds and people i "like" are masculine guys. i would believe it. psycology is one part brain make up, 1 part life experiences.
